The Best Time to Witness the Great Migration in Tanzania

The Great Migration is one of the most spectacular natural events on the planet, where millions of wildebeest, zebras, and gazelles move across the Serengeti in Tanzania and the Masai Mara in Kenya in search of food and water. The timing of this incredible event varies from year to year, so it's important to plan your Tanzania safari trip accordingly.

The Great Migration typically occurs between July and October, as the wildebeest and other animals make their way across the Serengeti in search of new grazing grounds. The exact timing can vary depending on a number of factors, including rainfall patterns, but this is generally the best time to experience this incredible spectacle.

During this time, you can expect to witness large herds of animals moving across the landscape, often accompanied by predators such as lions, hyenas, and cheetahs. It's an incredible sight to behold, and one that is sure to leave a lasting impression.

If you're planning a Tanzania safari trip and want to experience the Great Migration, it's important to book your trip well in advance, as this is a popular time to visit and accommodations can fill up quickly. Additionally, working with an experienced safari operator can help ensure that you have the best chance of witnessing the migration and getting the most out of your trip.

Great Migration dates tend to remain the same throughout the years. The first animals usually start to set out across the Serengeti in search of greener grass and dependable water supplies in April. Over the following months, they’ll encounter countless obstacles – from predators to river crossings – on their enormous trek. Here's a breakdown of their provisional travel schedule, so you can plan your own.

The Migration in Tanzania

December - March

At this time of year, the herds congregate in the Serengeti and Ngorongoro areas of northern Tanzania, which are made lush by the annual rains. This is calving season, and an excellent time for viewing newborn babies; while big cat sightings (and kills) are common. The southern Ndutu and Salei plains are best for spotting large herds during this time of year.

April - May

The herds start to migrate west and north to the grassier plains of the Serengeti’s Western Corridor. Seasonal rains make it difficult to follow the herds during this stage of their migration. In fact, many of Tanzania's smaller camps shut down due to impassable roads.

June

As the rains stop, wildebeest and zebra gradually move north and individual groups begin to form much larger herds. This is also mating season for the migrating wildebeest. The Western Serengeti is the best place to watch this stage of the migration unfold.

July

The herds reach their first big obstacle, the Grumeti River. The Grumeti can get deep in places, especially if the rains have been good. The depth of the river makes drowning a distinct possibility for many wildebeest and there are plenty of crocodiles to take advantage of their distress.

The Migration in Kenya

August

The grasses of the western Serengeti are turning yellow and the herds continue north. After crossing the Grumeti River in Tanzania, the wildebeest and zebra head to Kenya's Lamai Wedge and the Mara Triangle. Before they get to the lush plains of the Mara, they have to make another river crossing. This time it's the Mara River, and that too is filled with hungry crocodiles.

September - November

The Mara plains are filled to the brim with large herds, naturally followed by predators. The best place to stay while the migration is in the Mara is Governors' Camp.

November - December

The rains start in the south again and the herds begin their long trek back down to Tanzania to give birth to their young. During the short rains of November, the wildebeest migration is best viewed from Klein’s Camp.
